It’s possible that I shall make an ass of myself. But in that case one can always get out of it with a little dialectic. I have, of course, so worded my proposition as to be right either way (K.Marx, Letter to F.Engels on the Indian Mutiny)

Leader Approval. There have been some shifts in the approval ratings of the party leaders over the past three months. The proportion of Canadians approving of the job being done by Stephen Harper has fallen below the 50-percent mark for the first time since he became prime minister and now stands at 48 percent (down 6 points from March). Approval of Stéphane Dion has declined once again to 38 percent (down 2 points) and the proportion expressing disapproval of him has risen to 48 percent (up 5 points). Jack Layton has the highest approval rating of any of the party leaders at 56 percent (up 2 points), and a similar share of voters in Quebec approve of the job being done by Gilles Duceppe (53%, down 3 points). Approval of Elizabeth May has dropped three points to 42 percent.

Which leaves Dion as the dud. And it doesn't help when the dud chooses his doppelgängerto run. But then Dion has been more of a similcarum of a leader than a real leader.

This plays heavily in Outremont because Coulon was handpicked by Dion, who also blocked Justin Trudeau from the nomination, though some Liberals maintained Trudeau would have been the party's best hope in the riding, said Antonia Maioni, director of McGill University's Institute for the Study of Canada.

"Dion's claim was that he'd win back Quebec, and this is what potential Liberal voters are going to look at, and more so people in the party. If he fails to capture the riding, one of the safest Liberal seats in the province, it's not going to play well outside Quebec."

"Coulon is sort of Stéphane Dion's alter ego," said Antonia Maioni, a political scientist at Montreal's McGill University. "He's like Stéphane. An academic, quite reserved, very well spoken. And so in many ways, this is not only a by-election, but it's also a referendum on Stéphane Dion because he's chosen someone who resembles him the most."
